Use the ideas of energy and charge to explain why bolts of lightning are so much bigger than sparks from the Van de Graaff generator.

What is the energy in joules of a mole of photons associated with visible light of wavelength 486 nm?

What factor besides temperature affects the boiling point of water? a. mass b. number of moles c. volume d. pressure

Acertain reaction has a activation energy of 54.0 kj/mol. as the temperature is increased from 22c to a higher temperature, the rate constant increases by a factor of 7.00. calculate the higher temperature. c (report only numerical answer)
